@MWF/@ CHARLES F. WOLTERS, OF ROCHESTER, NEW YORK.

IM PROVEM ENT IN BATH-TU BS.

Spccication forming part of Letters Patent No. 212,081, dated February 4, 1879 application led J une 26, 1878.

such a manner as to make a closed chamber'` or vessel for condensed air or vapor baths, as shown in Figure 1 of the accompanying drawings.

A A A represent an ordinary bathtub. B B show the adjustable cover, constructed inl two sections, D and E, separating at the perpendicular dotted line a: in Fig. 1, and also Y shown in Fig. 2 at t t.

The cover B B is made high enough when placed on the tub A A to admit a grown person to the top of shoulders in a sitting posture. The difference in the height of different persons is regulated by an adjustable stool or chair, d. The top of cover B B vis provided with a round opening, m, the joint t t dividing the same. The round openin g m is made somewhat larger than the neck of a large person. Section D of cover B B has ahinged trap, a, opening to the inside, as represented in drawings, Figs. 1 and 3. Section D of cover B B is hinged at c c. (Shown in Figs. 1 and 2.)

To enter the bath-tub A A the section D of cover B B is raised perpendicular, while the rear section, E, of coverB B remains stationary. The patient before taking a seat in the tub A A adjusts the stool or chair d to the proper height, leaving his shoulder (when sitting on the stool or chair d) free from the top of cover B B, and the chin of the patient, which remains outside of tub A A, clear of the cover B B, as shown in drawings, Fig. 1. After the patient has taken a seat, the section D of cover B B is shut down. The trap abeing open or down, as shown by dotted lines p p in Figs. 1 and 3, will not come in contact with the face of the patient.

The trap a is provided with one o r more light bolts, 'n n, for the purpose of holding the trap a in a horizontal position when closed. The bolts a a are operated either by the patient from the inside or an attendant from the outside by means of aknob, o. At thelower end of section D of cover B B is an opening, q, covered by a hinged valve or cover, b. The valve or cover b is operated either by the patient from the inside or an attendant from the outside. A string, s, is attachedA to the valve or cover b, and brought to the inside through a hole, 7c, in easy reach of the patient. The opening g is for the purpose of admitting cold air tothe inside of bath-tub or ejecting hot air or steam from the inside of bath-tub A A. At the foot orA lower end of the inside of bath-tub A A are one or more atmospheric gas-burners, h h, which are supplied with gas from the outside by means of a rubber hose, z'.

u represents a movable water-tank, hung to the sides of bath-tub A A and immediatelyover the atmospheric gas-burners. lt can be easily removed if not wanted.

e represents a perforated movable partition, of either metal or wood, and is made to slide between narrow strips f j', fastened on both sides of the bath-tub, as shown in Fig. l.l

The movable partition e is for the purpose of preventing the patient from coming in con tact with either the gas-burners or the watertank.

Warm or cold water is admitted to the inside of chamber or bathtub by means of a rubber pipe, j, passing through the cover B B at 7c, and brought in easy reach of the patient.

The patients neck being smaller than the opening m, atowel or cloth is used to close up the space around the neck to prevent any heat or steam from escaping at that point, thus forming a closed chamber or vessel, which can be heated in a very few minutes, either by hot air or steam, to any desired degree.

I claim as my invention-v 1. The combination, with a bath tub or chamber, of an arched cover, constructed of two independent sections, one of which is hinged and provided at the edge adjoining the other section with a swinging or hinged piece to close upward around the neck of the patient, substantially as and for the purpose described.

2. The combination, with a suitable bath tub or chamber and the cover B, constructed in two sections, one of which is hinged at one end and provided with an opening, q, of the hinged valve b and zt device connected with vertically-adjustable partition e, arranged in said Valve and extending into the bath tub or front of said vessel and burner7 substantially chamber Within reach of the patient for operas and for the purpose described.

ating said Valve, substantially as and for the CHARLES F. WOLTERS. purpose described. Witnesses:

3. The combination, with the water vessel or GEO. FRAUENBERGER, tank and burner for heating the saine7 of the JACOB GERLTNG.
